Which components are needed for a boost?
The basic requirement for increased load is the installation of our additional air suspension. If not only the permissible total weight (GVW) but also the rear axle load is to be increased, a new wheel/tire combination with the appropriate load capacity may need to be installed. The load capacity of the tires and rims must be half of the intended axle load.
